Walther P38 9mm

Well this is the third time today i've tried to make a post and the other two were droped, lost in space.
Today I bought a Walther P38 in 90% condition. Broght it home and cleaned it . All parts fit tight and snug. The gun looks great. I bought 100 rounds of 9mm luger for the range tommorrow.

I am not sure what effect the ammo has to do with the hex pin since it is only to prevent excess wear on the frame when the slide is returning to battery. Still, that advice to use standard ammo is always a good one, even in those guns supposedly made for +P.
